tests: clarify test setup test in test-uncommit.t

I assume the "hg uncommit b" is there to prove that the working copy
is dirty before we try "hg uncommit --allow-dirty-working-copy b". It
seems clearer to put that check just before we run the actual test.

 Help for uncommit
 
   $ hg help uncommit
   hg uncommit [OPTION]... [FILE]...
   
   uncommit part or all of a local changeset
   
       This command undoes the effect of a local commit, returning the affected
       files to their uncommitted state. This means that files modified or
       deleted in the changeset will be left unchanged, and so will remain
       modified in the working directory.
   
       If no files are specified, the commit will be pruned, unless --keep is
       given.
   
   (use 'hg help -e uncommit' to show help for the uncommit extension)
   
   options ([+] can be repeated):
   
       --keep                     allow an empty commit after uncommiting
       --allow-dirty-working-copy allow uncommit with outstanding changes
    -I --include PATTERN [+]      include names matching the given patterns
    -X --exclude PATTERN [+]      exclude names matching the given patterns
   
   (some details hidden, use --verbose to show complete help)
 
 Uncommit with no commits should fail
 
   $ hg uncommit
   abort: cannot uncommit null changeset
   (no changeset checked out)
